Predictors of mortality in pulmonary contusion. Discussion.
Southwestern Surgical Congress. Annual meeting. Tucson AZ USA, 1994/04/17.
Associated injuries and central nervous system (CNS) trauma are historically associated with poor outcome in patients with pulmonary contusions, but the value of specific factors reflecting shock, fluid resuscitation requirement and pulmonary parenchymal injury in predicting mortality in this population is not well established.
The medical records of 100 consecutive patients with pulmonary contusion, admitted over a 5-year period, were retrospectively reviewed.
Survivors and nonsurvivors were compared in terms of age, Injury Severity Score (ISS), Glasgow Coma Score (GCS), PaO2/FiO2 (oxygenation ratio), the severity and adequacy of shock resuscitation reflected in plasma lactate, resuscitation volume and transfusion requirements, using one-way ANOVA.
To determine the contribution of individual, interdependent variables to mortality, the data were then analyzed using multivariable analysis.
ISS and transfusion requirement were significantly higher, and GCS and PaO2/FiO2 at 24 and 48 hours after admission were significantly lower in nonsurvivors than in survivors.
After multiple regression analysis, the factors most strongly associated with mortality included patient age, oxygenation ratio at 24 hours after admission, and resuscitation volume.
Outcome in patients with pulmonary contusion is dependent upon a number of variables including the severity of pulmonary parenchymal injury as reflected in PaO2/FiO2 ratio.
